Coding OCR with machine learning from scratch in Python — no libraries or imports! (From Scratch #2)

Our program uses the k-nearest neighbors algorithm to classify images from the mnist and fashion-mnist datasets, meaning it takes digits (1, 2, 3, …) and garments (shoe, t-shirt, …) and guesses what they are (classifies them). It can get up to 93% accuracy on mnist. I wanted this to be a simple introduction to machine learning for those not very familiar with it.

Because this is a recording of a live stream, you'll hear me sometimes talking to the chat.

What would you like to see me code from scratch next? Let me know in the comments! :)

Wishing you a swell day,
Vlad

He explains everything from scratch. This is the scratch I actually needed!

I've just started learning machine learning and I really like this video - you explain everything very clearly. It's nice to see how to do this from scratch instead of using some huge libraries.

most underrated software programmer and evangelist on youtube. i find this explanation/tutorial better than any other youtube video.

[youssef-attai]

I swear to god you are a legend, no one could have explained it better. Thank you so much.

Please don't get dis-heartened or demotivated, this video is a total gem (sorry too late for encouragement after 10 months) but this really helped, thanks bruv, keep up the good work

followed, that the from scratch thing everyone was looking for.

Brilliant tutorial, everything is so clearly explained, and it actually is from scratch.

This was so refreshing, you made it way better than some full-of-pride professors at some universities. Thanks so much mate. Could you do at some point the most basic “non-lazy-training” algorithm from scratch? Whichever you deem is fine

[ruoyuguo]

Thanks for sharing, PaddleOCR seems friendly for training the OCR models. Could you please shoot a video about how to use PaddleOCR?

I was looking around for this stuff, it's amazing, You nailed it
clumsy computer, can you please implement hyper parameters in it ?

[adhamsalama]

This is amazing! Thanks for this awesome video! Subscribed!

603. you deserve more, I hope you'll get soon

Hey, the website you've got those files from now requires a password and username to get in. Is there another place we can get the files from?

Instructional video about machine learning, it would be good if you could make a video on how to configure vi with python with the basic instructions. Best regards.

[trungthanhbp]

where are you now, we need your video :D

How to preprocess a image of PNG file format downloaded from the web to recognise the digit and what changes to do in read images function in the above code to test that image

[jonas]

why did you stop dude, your explanation is so well

[hemantchauhan]

NEED HELP! I am making a website where user can upload a pdf but I want that pdf to upload only if that pdf has images of only HANDWRITTEN text. Thank you for reading.

[PrakashKing]

Do you have solutions for alpha numeric recognition I have tried all the method finally I’m getting fail tesseract easy ocr etc for example ABC00OO1 and SI1234H

[xhyhbdka]

Good video but christ, presentation wise and viewer experience, an absolute car crash!! Max res 720P, you should have zoomed a bit more!!! That background chance from black to white just fucked my eyes up at 14:25
